Moving Equipment to the Setup Position
Use the wireless hand-pendant or remote positioning controls in Auto mode to move
the patient positioning devices to the Setup target position, as described in Chapter 9
and Chapter 11respectively.
When a device reaches the Setup position the hand-pendant or the remote
positioning controls beep one time.
CAUTION The patient may only be loaded onto the couch when the surface of the
couch is flat, i.e., when pitch and roll angles are equal to zero.
Important Verify the weight of the patient on a day to day basis. If the patient
weight changes by more than 10 kg, the correction vector shall be
recomputed for the table plate associated to the patient.
CAUTION Using the long couch extension with the Patient Positioning System
(PPS) for vertex fields in a Gantry Treatment Room (GTR) is not possible
because of a mechanical interference between the couch and the
nozzle.
In order to avoid the risk of collisions, a short table-top must be used.
WARNING Make sure that the DID flat panel arms are fully retracted before
attempting to move Patient Positioning Devices (PPDs) that can collide
with the flat panels.
